Accurate:Unlike other similar applications PageRank extension provides accurate results. Rank reported by PageRank is the same as rank reported by official Google Toolbar.

Lightweight:PageRank does only one thing and does it very well. PageRank extension is lightweight and not overwhelmed by various unneeded features.

IMPORTANT NOTICE:This extension was programmed to display the same rank as official Google Toolbar. So, if extension displays "none" rank - most probably, this is because Google Toolbar also shows "none" for this URL. If extension always displays rank of home page for some sites - most probably, this is because Google Toolbar also shows rank of home page for those sites. But if anybody will find URL for which rank reported by extensions is different from rank reported by Google Toolbar - please report it and it will be fixed on highest priority.
